Is this trial a fit for you?
✓Likely a good fit
Ideal candidates include any patient diagnosed with stomatocytosis, regardless of age, who is affiliated with French Social Security.
✕Probably not a fit
Patients whose stomatocytosis diagnosis has been excluded by ektacytometry or genetics may not benefit from this study.

What this trial studies
This observational study aims to create a comprehensive cohort of patients diagnosed with hereditary stomatocytosis, a rare genetic condition affecting red blood cells. Patients will be prospectively included, and their clinical and biological data will be collected during routine follow-ups by their hematologists. The goal is to enhance the understanding of the disease's presentation and progression, ultimately improving diagnosis and management strategies for affected individuals.
Why it matters
Potential benefit: If successful, this study could lead to better diagnosis and management of hereditary stomatocytosis, improving patient outcomes.
How similar studies have gone: While there is limited data on similar cohorts, the establishment of comprehensive registries for rare diseases has shown promise in improving patient care and outcomes.
